Y., assignor to Continental flanCompany, Inc., New York, N. Y., a corporation of New York ApplicationNovember 21, 1944, Serial No. 564,457

The invention has to do with a can filling machine and more particularlywith the construction of the pocket provided for measuring a desiredquantity of liquid product preparatory to discharging the same into acan.

In my copending application Serial No. 471,272, filed January 4, 1943,now Patent No. 2,362,793, issued November 14, 1944, there is shown anddescribed a machine for filling cans which includes a tank havingassociated therewith a series of pockets which are filled from the tankand then closed, after which the measured content in the pocket isdischarged into a can. Each pocket consists of inner and outertelescoping sections which may be shifted relative to each other forvarying the size of the measuring pocket and which may be separated fromeach other to facilitate cleaning of the same.

An object of the present invention is to provide a sealing means betweenthe telescoping sections of the pocket which permitsthe two sections tobe shifted relative to each other or to be separated and reassembled,which sealing means provides a very tight connection between saidtelescoping sections when placed in a desired set position.

In the drawings Figure 1 is a view in vertical section showing a portionof the filling machine and embodying the improved sealing means used inconnection with the telescoping sections of the measuring pocket.

Figure 2 is an enlarged vertical section through the two telescopingsections and the sealing means therefor.

The filling machine includes a center supporting column to which isattached a tank I, a portion of which is shown in Figure 1 of thedrawings. This tank has a bottom wall provided with a series of openings2 therein. Associated with each opening is a measuring pocket whichincludes an inner telescoping section 3 and an outer telescoping section4. Disposed in the tank is a cover plate 5 which remains stationarywhile the tank is rotatable. This stationary cover plate closes theopenings 2 in the bottom of the tank at certain times in the rotation ofthe tank. The invention has to do with the construction of a measuringpocket and it is not thought necessary to go further into detaileddescription of the tank and the manner of filling the pockets from thetank.

The outer section t of the measuring pocket is provided with a flange '6which rests upon a support I carried by the center column. At the 1Claim. (Cl. 226-98) lower end of the outer section is a valve body 8which has an inner bore corresponding to the bore of the outertelescoping section 4. The lower. end of this valve body is closed by aplate 55 which is preferably formed integral with the body member. Thisplate 9 has a series of discharge openings Ill therethrough which arecontrolled by a valve ll yieldingly pressed against the under face ofthe plate by a spring l2. The valve body is provided with a flange l3.Bolts i i extend through this flange and are threaded into the support7. Bolts [5 extend through the flange 6 at the lower end of the outertelescoping section 4 and are threaded into the support 7. Thus theouter telescoping section 4 and the valve body 8 are rigidly securedtogether and to the supporting member 7 therefor.

The inner telescoping section 3 and the outer telescoping section 4 aredimensioned so as to provide a close fit with sufficient tolerance topermit the sections to be readily shifted axially of each other or to beseparated and reassembled for cleaning purposes. The upper end portionof the outer telescoping section is threaded as indicated at it. A capI7 is provided with a depending skirt which is likewise threaded so asto cooperate with the thread IS, on the outer telescoping section. Thisserves as a connection between the cap and the outer section 4. This capH has a portion l8 which overlies the end wall 19 of the outertelescoping section 4. There is an opening through this cap which isdimensioned so as to fit the outer diameter of the inner telescopingsection with suflicient tolerance to permit the shifting of the innertelescoping section endwise of the cap.

Located within the cap is a metal ring Zil. This ring is dimensioned soas to fit closely the outer diameter of the inner telescoping section 3.This ring is also dimensioned so as to overlie the greater portion ofthe end wall IQ of the outer telescoping section 4. A ring gasket 2| isplaced between the metal ring 20 and the end wall I9. This ring gasketis so dimensioned that when the cap is turned onto the outer section soas to cause the metal ring to forcibly clamp the ring gasket against theend wall l9, said gasket will be forced laterally into very intimatecontact with the wall of the telescoping section 3 and this will make atight fluid joint between the two telescoping sections.

Means is provided for relatively adjusting one of the telescopingsections relative to the other for varying the capacity of the measuringreceptacle. This is accomplished preferably by loosening the capslightly so as to release the gasket and then shifting the parts to thedesired position, after which the cap is turned down so as to againforcibly press the gasket against the end wall of the outer telescopingsection and thus deform the gasket suificiently to bring about a tightsealing connection with the inner telescoping part.

When it is desired to clean the measuring pockets, the cap is loosenedso as to free the gasket and the telescoping sections are separated.This may be done by suitable means for raising the tank and lifting theinner section free of the outer section. When it is desired toreassemble the parts, the inner telescoping section will be lowered intothe outer telescoping section to the desired extent and then the capwill be turned down to seal the joint between the two telescopingsections.

It is obvious that minor changes in the details of construction may bemade without departing from the spirit of the'invention as set forth inthe appended claim.

I claim:

In a filling machine, a tank and a measuring 25 2 353 0 uring pocket andseparable from each other for cleaning purposes, said outer sectionhaving a cap threaded on the outer end thereof and overlying the endwall of said section, said cap being provided with an opening throughwhich the inner section passes, a metal collar disposed within said capand dimensioned so as to make close but sliding, contact with said innersection of the pocket and overlying said end wall, a ring gasketdisposed in said cap between the end wall of said outer section and saidmetal ring, said ring gasket being dimensioned so that when pressedbetween said metal ring and said end wall it will be deformedtransversely of its axis and forced into sealing contact with said innertelescoping section;
